In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted for each indent level.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted between the elements of an array, in expressions, method declarations, and method calls.
Keep indents on empty lines
If this checkbox is selected, PyCharm retains indents on empty lines as if they contained some code. If the checkbox is cleared, PyCharm deletes the tab characters and spaces on empty lines.
